Abstract
Aquatic insects are highly diverse and
abundant in freshwater ecosystem, and essential for maintaining the food chain.
The present study was carried out to record the aquatic insect diversity in two
selected water bodies of Chirang district, Assam, Northeast India. Altogether
22 species belonging to 5 orders and 13 families were reported during the month
of December 2023 to July 2024. The specimens were collected by using sweep net,
bare hand, jars and other standard methods respectively from two water bodies.
During the survey period, aquatic insect was abundant from order Hemiptera (10
species), followed by Odonata (5 species), then the order Coleoptera (4 species),
and followed by Diptera (2 species) then Ephemeroptera exhibited the least (1
species). Hemiptera showed highest diversity and dominant order of aquatic
insect represented by 6 families and Order Ephemeroptera revealed less visual
abundance from the study site. Water body in rural site showed high species
richness in contrast to urban site water body. Overall results revealed high
aquatic insect diversity in the present study area. This preliminary study will
provide insights into aquatic ecosystem for future work.
